The answer is b

Explanation:

The infrared (IR) range spans #0.7mum to 1,000mum#.

The near IR is #0.7mumto2mum# and the medium IR #2mumto25mum# (source vary on this).

In the context of Chemistry, IR is used in vibrational spectroscopy, and looking back at some of my old university text books (Organic Chemistry, Pine) the traces for these were in the #2mum to 16mum# region.

Hence the answer is b.
